Shuttle ST62K (aka Zen) Fan issue

Like a lot of users, i get an issue with my fan on the Shuttle Xpc. In fact, i found a lot of comments over the net, that Shuttle used some bad fan in this boxes. Some users decide to use the waranty, but i don’t want to send this back to Paris, just to have another crappy fan.

I decided to change it by myself. But finding the right fan is really hard, because it’s 80mn x 80mn x 1.5mn fan. After a long search i decided to go to a tunning shop. (They have a bunch of various CPU fan).. The guy said to me: Ok, No problem. We have a video card fan that can feet .. Oh really a video fan ?

Here in Switzerland is very difficult to find the original, bad, Shuttle fan but I found an excelent distributor for the ZM-OP1 fan : "Brack Electronics AG". They sent to me the Zalman fan in 24 hours!

My first Zen (with a Bi-Sonic fan) had the "fan header" issue so I got it replaced with a new one. Unfortunately the new Zen had a loud-as-hell-spinning-at-2800-rpm-all-the-time fan by Adda. I just replaced the fan with a ZM-OP1 and now my Zen is quiet again! :D

I am having a fan failure as well on my Shuttle ST62K. It looks like it’s the second time because the first time I took the machine to service and they said it was a fan contact problem. My point is: should I change the fan as it is being suggested or I try some tweakening like changing headers from fan 1 to fan 3 (maybe it was done the first time or the changed the old defective fan).
CPU temperature is over 90° I run the PC with open case, but sometimes it does stop functioning…or I could see the fan moving a bit but not running…

I have just ordered a new fan that the old one started to work again being connected to Fan 3 without Smart fun but just on Full speed. The point is that it started to work at a CPU temperature which is not the tag of 65° at rpm over 4000. So I moved to Smart Fan again and it does not work! I move back to Full and it does not work anymore either…Everything seems random…

Massimo, this is normal in fact. Your fan isn’t totally dead, but only used. It has issue to start so, if you make it run at the full speed, it has a larger current in, so starting is easier. This doesn’t change anything you need to change it anyway. A little trick you can use, simply make Smart Fan starting sooner, I mean set it to 40° or less. By this way, it will run faster, but this is only a trick, soon you will need to run it a full-speed permanent, until it won’t work at all.

Nice suggestion. The Zen ‘Sm@rt Fan’ issue has been effecting my Zen and is much worse now that I’ve dropped a Prescott into it. Setting the BIOS to full is the only way to prevent the intermittent smart fan from letting the CPU hit 87 C!

Maybe this fan will make the racket bearable (and only $8.99 now at NewEgg)

After a period where my old original FAN had resumed working properly, now it is dead again. I had bought the Zalman ZM-OP1 and I have just connected it but it does not work either. No full speed, no smart fan, no Fan 1 and Fan 3…no way to tweak temperature tag to start at lower temperature than the fixed 65° C°.
The only thing which works so far is a big fan close to my Shuttle open case…

I guess your ZM-OP1 has an issue. The ZM-OP1 come with a molex adapter (for poeople which use them on a barely PC), simply use this adapter (smart fan won’t work of course) to check if your ZM is Ok or not .

If you speak french and have a MSN account, leave me a message perhaps I can help.

Here last news:
The old original fan still works fine conncted to Fan/header 2 (I have just prolonged the cables connections). The smart fan is on and it looks like the fan is turning around 1620-1650 rpm (I have installed Speedfan 4.32 software to monitor it). The CPU temperature is still around 61-62° C so it has not yet triggered any fan speed increase being below the 65° tag in BIOS.

I cannot modify the Bios setting concerning the trigger temperature. It looks fixed. The windows pop up for the change but then it does not seem possible to change (and there is an asterisk next to the temperature line.).

My fan stopped working a while back. In talking to shuttle they said to try to plug it into a different plug on the motherboard (sorry I don’t know the right technical terms) — there it worked so it wasn’t the fan. They suggested this was cheaper than fixing the motherboard.

Now, that second power point has gone dead — neither now works. Any ideas?

Hi, Josh. I guess Massimo has the same issue in fact. You blew up the fan driver on the motherboard. So, they ask you to use another plug, and now blew up your second driver. If I remember there is 3 plug on the mother board.. perhaps, the 3th will work.

But take care your fan. I mean, fan drivers should’nt blow up right this. I’m quite sure, your fan is dead. A dead fan has some issue to start, and usually drew a lot of power from the driver (to start).. => kill the driver.

If there is no 3th plug, you can plug the fan on the PSU directly with wire that come from a new fan. Of course, smartfan won’t work, but …
